The ear sock and nose piece are different on the Mag M Frame. The shape of the ear socks is different on the Mag M Frame from the regular M Frame, also the nose piece on the Mag M Frame is slotted and the regular M Frame is smooth.

The ear socks took the most amount of time and pressure to put on. The new ones are skinnier and flat on one side compared to the old ones.
